Safe System of Work for Equipment at Height

Safe System of Work for Equipment at Height Introduction Construction industry’s industrial accidents is more than other industries. The accident rate per 1000 workers was 35.9. Among which the highest number of deaths involved in working at height. Which were related to â€Å"fall of person from height†. Working at height in the construction work involving of temporary or transient working environment condition means a lot of inherent hazards and potential hazards. Construction work, safety in the work place is very important, it is essential. Therefore, must take the necessary security measures to ensure the safety operation. Background I am a manager of the Engineering Department of Excellent Property Management Limited. Recently, I observe that fatal accidents involving working at height is a major trend in 2013. While the workers of our company and the outsourced contractors in the estates and plazas are using various facilities in performing their jobs in working at heights. Objective A study of four commonly used equipment for working at height: ladders, mobile type tubular scaffolds, elevated working platforms and bamboo scaffolds. Analyze their function, limitations, risk and encountered in the work processes. Provide relating local safety legislations, Codes of Practices and guidance to the workers. It should to develop for the safe system of work. Which procedural inspected work tasks to find the potential hazards, Inherent risks. Providing the safety and heath policy or strategies in controlling the hazards and demonstrate the understanding of common health and safety management system. Equipment for working at height The common of equipment in working at height: ladders, mobile type tubular scaffolds, elevated working platforms and bamboo scaffolds. Ladders Ladders are the most common ancillary tools for working at height. A simple tools for gaining access to higher levels. Therefore, involving highest number of workers are injured while working at height. Functions of ladders: Portable, easy and convenient. Widely used in various construction units. Easy storage Limitations for use of ladders: Inspect the ladder before every times and regularly afterwards. Must check the ladder side and ladder steps has burst, it has broken rung ladder before use, and whether there are loose or anti-slide pedal to lose and so on. Indicate whether the ladder meets safety standards. Pay attention to the ladder’s safe working load, make sure not to exceed the load when using. Where a handhold is available on the ladder. Ladder placed on a firm and level ground Ladders must be firmly in supporting the matter, if not fastened to the ladder, the ladder should be located under one reference help. Ladders only for 2 meters below the lightweight work Not suitable for long duration or high frequency for work at height. Not suitable for long duration or high frequency for work at height. At a height of 2m or more, ladders only be used for access and egress, and not a place to work During ascent, work and descent on ladder, worker should be capable of retaining three points of contact with the ladder. Ladders must be at the proper angle eyes on the supports, the angle is too large or too small can lead to accidents. Strict compliance with the manufacture’s instructions and safety warnings. Risk for use ladders: fall of person from height The footwear is from mud or grease before climbing up a ladder. The ladder is unstable and resting on an uneven and soft soil ground. The insufficient space behind the steps to provide a proper footing. Never overload the ladder, more than one person is working from a ladder Which should be avoided as far as possible for using ladders: Use any ladder that is already bent or ladder steps has burst Connect short ladders together to form long ones. Overstretch the body to either sides of the ladder. Position the ladder at the place where working Paint something on ladder to cover up crack and defects. Ladders are used as a working platform. Not following the manufacture’s instructions and safety warnings. Not compliant with international safety standards. Training for worker: The worker for use ladder must have related safety training or supervise to guidance to the workers. The correct technique for climbing of ladder. (Three-point contact) Elevated Working Platforms The elevated working platforms is very convenient for ancillary tools for working at height. This is considered to be work equipment that prevents a fall. It is a manned to working at height, such as ceiling maintenance work , repair and cleaning the height air conditioning, lighting or external wall. Limitations for use of elevated working platform: Consider the work requirement the carrying capacity, height of elevation, mobility and stability. The elevated working platform should be match for operation site, on the road and environmental conditions and limitation. The safety passageway for access and egress from the elevated working platforms The important point is the manufacturer or the agents company provides training course on operations, inspection, identify risks, initial fault strain, Fault reporting mechanism and operation of the elevated working platforms. Start to inspect and test the platform before use every time Calculate and record the every time loading weight for manned and equipment to be ensure not exceed the limitation maximum safety work loading. Ensure the elevated working platforms have guard-rails is hard, stable and secure. Has a slip-resistant floor. Install of the toe-boards round at the edge of the platform. Ensure the operation is horizontal level during the rising and falling, does not occur uneven phenomenon. Enclosed working area of the elevated working platform to avoid endangering others persons Must wear safety harnesses with lanyards securely attached to platform’s anchorage points. Risk for use elevated working platforms: Fall of person from height for guard-rail loose or broken. The workers by injured on elevated working platform due to the platform move. The elevated working platform and worker are falling due to exceed the limitation maximum safety work loading. Which should be avoided as far as possible for using elevated working platforms: Move the elevated working platforms when the workers still on it Not secure all guard-rails of the elevated working platforms. Excessive dependence and sit on guard-rails of the elevated working platforms. Riding on the guard-rails up to higher level for working. Lean over out of the work platform outside. Ignore the examine, test and maintain the platform regularly. Work in the absence of adequate of adequate training and instructions Training for worker: The worker for use elevated working platform must have related safety training or supervise to guidance to the workers. The worker should be have the following knowledge, before starting to work: detailed safety operating procedures specified by the manufacturer; limitations on using the elevated working platform; limitations on working loading; items to check before using the elevated working platform; and demonstration and practice on the operating procedures. Mobile type tubular scaffolds Mobile type tubular scaffolds is for temporary structure to support work and access platforms. Mobile type tubular scaffolds can be used for different purposes in different construction activities. To building, dismantling and modifying of scaffolding must be carried out in compliance with the Construction Sites (Safety) Regulations and Codes of Practice for Bamboo and Metal Scaffolding Safety of the Labour Department. Limitations for use of mobile type tubular scaffolds: The safety passageway for access and egress from the mobile type tubular scaffolds. Suitable tail: 900mm – 1150mm top rail, 450mm -600mm mid rail and minimum 200mm high toe board. Toe boards must rise at least 200mm. Has a fencing and outriggers in mobile tower Not suitable for outdoor work in strong winds and inclement weather. Provide enough supporting point to fixing the scaffolding to the building. That could have an adverse effect of weather conditions on the scaffolding work should be constantly monitored and should be taken and provide to maintain the stability of the scaffold and the plant, equipment and works. The Scaffolding should be provide and setting with double guard rails and toe boards. Additional measure such as nylon net is also required to prevent materials, tools or equipment falling. The boards and planks should be unpainted so that any defects are readily visible. To building, dismantling and modifying of scaffolding must be conducted by trained worker under the immediate supervision of a competent person. Boards and planks used in the construction of working platform should be protected against splitting. Mobile type tubular scaffolds placed on a firm and level ground, on different ground surface require different support: Hard surface – is sufficient hardness and thickness to support the scaffolding, but preferably to be placed on a base plate. Other surfaces – is any type of flooring or paving which would be penetrated by a standard with a base plate beneath it or if there is doubt about the surface, should be used base plates or metal packing plates at the bottom of the standards. The supports for a scaffold should be maintained in an adequate condition during the life of the scaffold. The width of working platform of the scaffold not less than 400mm. The group of boards across the width of the scaffold should be consistent with the same length, with all boards of the same thickness. The angle of ladder for the ratio of vertical with horizontal level not more than 4 to 1. Risk of toppling when using mobile type tubular scaffolds: Over the carrying capacity for the top of the working platform. A ladder is placed on the top of working platform to extend to gaining access higher level. The tower is placed on sloping or uneven ground. Which should be avoided as far as possible for using mobile type tubular scaffolds: Move the elevated working platforms when the workers still on it Climb a mobile type tubular scaffold when the wheels are unlocked. In windy or severe weather conditions to use a mobile type tubular scaffold for outdoor work. Move the mobile type tubular scaffold when workers or materials still on the working platform. Training for worker: A trained workman has satisfactorily completed a formal training in metal scaffolding works equivalent to any of those mentioned for a competent person or has satisfactorily passed the intermediate trade test for metal scaffolder of the CICTA and possesses at least 1 year of experience in metal scaffolding works. (Under the Construction Workers Registration Ordinance). Inspected by a competent person before being taken into use for the first time. Inspected by a competent person at regular intervals not exceeding 14 days immediately preceding each use of the scaffold. In respect of scaffolding safety, the worker are subject to the requirements of the following regulations: 38A, 38AA, 38B, 38C, 38D, 38E, 38F, 38H, 38I, 48, 49, 52, Bamboo scaffolds Bamboo scaffold is a temporary structure to work and access platforms. Common in the construction , renovation and repair work. Bamboo scaffold use natural material, cheap and can be recycled. While its flexibility suitable for use on any project, workers can quickly change or bamboo cut to the desired length and shape. Bamboo is lightweight, easy to transport, erect and modify and dismantle is shorter time than other type scaffolding. Limitations for use of bamboo scaffolds: Erection and dismantling the bamboo scaffolding must be in compliance with the Construction Sites (safety) Regulations and Codes of Practice of Bamboo and Metal Scaffolding Safety of the Labour Department. The bamboo higher than 15m, should be designed and approved by professional engineer. Should be provide sufficient support point to secure to the bamboo scaffold with the building or structure to prevent collapse. For avoid materials from material, tools and debris from falling should be erect catch-fans, nylon net and protection screen at the bamboo scaffold. Ensure the Form 5 is duly signed and valid. Suitable tail: 900mm – 1150mm top rail, 450mm -600mm mid rail and minimum 200mm high toe board. Risk of using bamboo scaffolds: Toppling when over the carrying capacity for the bamboo platform. Material or tool from falling when no provide sufficient additional measure to prevent from falling. Toppling when no provide sufficient measure to secured the bamboo scaffold to prevent severe weather. Which should be avoided as far as possible for using bamboo scaffolds: In windy or severe weather conditions to use bamboo scaffold for outdoor work. Working when the bamboo scaffolding is unfinished state. Use incorrect and unsafe method to dismantle bamboo scaffolds. Avoid the demolition bamboo falling on the ground directly and immediately, workers should be one pass one or use vertical transport measure to the ground. Training for worker: Erection, alteration and dismantling of bamboo scaffold must be conducted by trained workmen under the immediate supervision of a competent person.

Legalizing Marijuana in society

Legalizing Marijuana in society Legalizing Marijuana While most people recognize only the negative and harm that goes with marijuana use in society, there are several positive effects that are being ignored. In an essay written by Carl Sagan (1969), an advocator for legalizing marijuana, he states, â€Å" The illegality of cannabis (marijuana) is outrageous, an impediment to full utilization of a drug which helps produce the serenity and insight, sensitivity and fellowship so desperately needed in this increasingly mad and dangerous world.† Too many persons, marijuana users and even those who dont use the drug share similar sentiments. States like California have begun the quest for legalizing marijuana after many debates. Marijuana or cannabis as it is commonly called is a green or gray mixture of dried, shredded flowers and leaves of the hemp plant Cannabis sativa. It is smoked by rolling it in tobacco paper or putting it into a pipe. This drug is consumed by a great number of people around the world. There are over two hundred slang terms for marijuana including pot, herb, weed, boom, Mary Jane, ganger and chronic. The drug has always been considered an illicit drug ever since Harry Anslinger made false remarks at a hearing in 1937. However, many people cultivate it on a small or large scale for sale to the public and people in turn purchase it for use as a form of recreation and even medical reasons. Although from all accounts, many persons consider marijuana to be the least harmful drug among others, including alcohol and cigarettes, it is forbidden by law in many countries and parts of the United States of America. Some commonly committed drug crimes include possession of the drug, possession wit h the intent to sell, cultivation of the drug; drug trafficking, manufacture and distribution. Supporters of the criminalization of marijuana in the United States consider the use of the drug a felony and the laws governing marijuana are as rigid as those regulating cocaine or heroin. Users of the drug and even non-users request that laws be modified to alleviate the penalties related to its conviction when one is charged, or to have the drug legalized. It is proven that among all the crimes related to drug use, there are fewer crimes related to that of marijuana use. The Office of National Drug Committee in its report on the number of persons in jail for drug related crimes states that marijuana accounts for just 13 percent of all drug state offenders. From a broader prospective of the entire prison population, it was noted that marijuana was involved in the conviction of 2.7 percent of all state inmates. About 1.6 percent of the state prison population was held for offenses involving just marijuana while just 0.7 percent was incarcerated with marijuana possession as the only charge and 0.3 percent was first time offenders. It is claimed by the supporters of the legality of marijuana, that the drug stimulates crime in society. Yet, they ignore the simple fact that it is because of the strict but deteriorating law enforcements imposed on the use of the drug that encourages these simple crimes. An expert supports this in the following words, If marijuana users are no longer jailed for possession of the drug, lots of room will be opened up in our already overcrowded prison systems for more hardened offenders such as: murderers, rapists, child molesters and other violent criminals. The judicial system will no longer be burdened by having to trial cases involving marijuana. As a result, the police will be able to allocate more resources to solving more violent crimes. Since marijuana could therefore be purchased at any drug store after being legalized, violent crimes such as: robbery, drug warfare, contamination of drugs by other substances such as LSD, PCP and cocaine could quickly become a thing of the past (Saldevar, J., 2006). It is stunning to note the number of persons admitted in hospital emergency rooms due to the use of alcohol and cigarette (tobacco) use legal drugs. The following are statistics on alcohol vs. marijuana use. Records show that 100 thousand deaths annually are directly linked to acute alcohol poisoning while in 4,000 years of recorded history no one has died from marijuana overdose. It is also stated that alcohol causes physical and psychological dependences as well as temporary and permanent damages to all major organs of the body. Marijuana therefore, is a much less violent provoking substance than alcohol. It can be confirmed by hospital authorities that there are few or no marijuana related illness in their emergency rooms, while billions of dollars are spent on other illnesses, and this is worldwide. Therefore, it should not be maintained that this drug be considered a public threat. Marijuana legality will instigate cultivation and sale on small or large scale farms. The high demand for this drug will be met with governments gaining from taxes and licenses from the farmers. There will be no more drug-trafficking or smuggling of marijuana but instead shipping companies to profit from such activities. This multi-billion dollar industry will by no means fail the economy, once it is regulated. Currently, the governments are at a loss simply because it is already a growing industry that they are not gaining from. The revenues that will be derived from taxes can bring much needed relief from debts of the economy. Other segments of the country including education, health, and security among others, will have better programs as a result of sufficient or perhaps overflowing funds disbursed throughout the country. Employment will no longer be an issue once this new drug industry has been controlled. With such major investments waiting and the creation of employment certain, drug dealers or cultivators can now be equated to sales men or businessmen. Standard of living in the country or the world by extension will surely be thriving. Opponents of the legalization of marijuana should not deprive any county from such economic gain. While critics claim that marijuana should not be decriminalized, advocates maintain strongly that if the drug is regulated and taxed like other goods such as alcohol and tobacco, it will now become a product with major economic and medical benefits. Companies involved in the manufacture and packaging of the drug will adhere to all government and federal standards. This will include appropriate labels such as ingredients listings and disclaimers placed on packages so as to advice and warn users of its contents. These should be clearly and strategically placed on each package with supervised dosages recommended by federal and medical advisors. In that way there may be no case of misuse and the drug will be kept out of the reach of minors. When such health standards are put in place, the onus will be on the companies involved to adhere to regulations of the state. Legal drugs like alcohol and cigarettes can be out of reach for minors because they are sold in stores who need licenses. These stores have an incentive to sell only to adults in order to keep their license. There should be similar incentives for marijuana dealers. To protect our children we must give these marijuana dealers an invitation not to sell to them illegally. This cannot be done in a system of marijuana prohibition because we cannot take a license away if we did not give it out. To alleviate the many social and economic issues that stem from marijuana use, it is crucial that the drug be regulated and controlled. A freelance writer shares the same sentiments in an article by saying â€Å"If we take marijuana off the streets and regulate it, we will diminish organized crime problems† (Marshall, 2005). Advocators will agree that the negative effects caused by marijuana use are only increasing because of the laws against it. Such a controversial issue can be dealt with so easily with much to gain from. It is high time that young men on the streets became professional business men in the thriving industry that they are all passionate of, yet suppressed by law enforcements. It is the economys current state that has given people incentives to seek financial relief and recreation in marijuana use. It is now the economys turn to attain much more. The rewards from legalizing marijuana are unlimited. The end of all poverty and government debt lies in the hands o f those who keep this harmless drug prohibited.

Events that Led to the Civil War Essay -- American History Papers

Events that Led to the Civil War There were several issues that contributed to the split between the northern and southern states. Among these were the deep social, economic and political differences. The split could be traced as far back as the early 1800’s, just as the industrial revolution was beginning. It’s effects on the north and the south caused the economic split. As the north was becoming more industrialized; the south began to rely heavily on slave labor. This was one of the main reasons, as the southern view on slavery differed greatly from the North. These views were based on drastically different interpretations of the constitution. In the north, machines, interchangeable parts, and mass production were fast becoming a way of life. Northerners began building factories for mass production. These first factories were used for making textiles and later evolved to manufacturing a wide variety of goods. This created several opportunities for jobs. And with immigrants flooding in from Europe, finding employment was no problem. The factory system was efficient and inexpensive for the north to employ a large work force. In the south, cotton was becoming a huge success for the southern farmer. Cotton, being a very laborious crop, required the ownership of many slaves per plantation. Unlike the immigrants of the north, slaves were property. Slaves were also much less of a profit. When a slave became ill he could not simply be replaced, he needed to be cared for, after all, this was the plantation owners property. On the other hand in the north if a worker became to ill to work, there were several immigrants waiting for the job. In 1818, the balance of power in congress was equal... ...was not ratified by the necessary number of states. The existence of slavery was the central element of the conflict of the north and south. Other problems existed that led to this succession but none were as big as the slavery issue. The only way to avoid the war was to abolish slavery, but this was not able to be done because slavery is what kept the south running. When the south seceded it was said by Abraham Lincoln that â€Å" a house divided against itself cannot stand. I believe this government cannot endure permanently half slave and half free.† Because slavery formed two opposing societies and slavery could never be abolished, the civil war was inevitable. These were all the reasons why the south seceded from the union, this succession was eminent and there was no plausible way to avoid it.

The Economics Today   Ã‚  Ã‚  Ã‚  Ã‚  The opening bell on the floor of the New York Stock Exchange September 17, 2001 was a ring that no one was sure about. The Stock Exchange had not been open since the tragedies that occurred on September 11, and many were skeptical about how the market would fare on its first day of trading.

How Has Pop Music Changed over the Last 80 Years Essay

Over the past 80 years, pop music has changed largely due to many reasons. For example, our technology has developed majorly, resulting in auto tune being overused by popular artists of this generation, along with the change in the way we regard music now. Also, the genres of music that are now popular have changed, and rap and alternative/indie music have advanced massively in popularity. To begin with, technology has progressed a great deal, which has influenced music produced recently. An example of this is auto tune, which has been used by countless artists; Rihanna, Chris Brown, Ke$ha, Kanye West and Justin Bieber are only a small number of these. This means that music these days is much less natural, and artist’s voices are often entirely altered. Another way the development of technology has changed how we listen to pop music, is websites on the Internet such as YouTube, which allow us to explore different genres of music much more easily. Since TVs, radios, and cellular devices have been made more accessible, advertising for new music has become much more common, this means that we are introduced to new genres and styles of music. The development of technology has provided us with an overall easier access to music, and has opened us to different types of music that we would not have originally listened to. It also provided artists with a chance to use new types of editing to change the sound of their music. Music is popular with children, teenagers and adults. More often than not, teenagers are seen with mp3s and earphones, but children are often singing music from TV shows, and adults singing songs from ‘back in the day’. In the 50s, pop music stopped being a genre listened to by children and adults alike, but started being specifically for teens. Artists like Justin Bieber, One Direction, Elvis and The Wanted used sex appeal to make their music sell. Elvis was nicknamed ‘Elvis Pelvis’ for the way he moved his hips, and most boy bands are known better for their good looks than their music. Younger artists are now coming in with new music, and their music is appreciated more by teens who feel more of a relation with them, because of the closer age gap.

Hca/210 Final Project Wk 9

My Proposal for a New Health Care System Alyssa Zacharias HCA/210 March 28, 2010 Joan Lewis {pcut:paragraph_to_cut} A vision for a new health care system would be guaranteed affordable health care to all Americans. Our medical care is good, but the system which the care is financed is extremely inefficient, unfair, and extremely bad. Americans remain uninsured, due to the high cost of health care coverage, not just to the family finances, but to corporate American’s bottom line as well. The United States spends much more share of its economy on health care than any other nation, and yet has failed Americans with the one thing that health insurance is suppose to provide: health security. To avoid recurring dismissal of previous campaigns, this new health care system will provide a successful agenda taken seriously the political constraints, and organizational realities that have hamstrung reform efforts in the past. This system will build on the most popular elements of the present structure; (Medicare and employment-based health insurance) making changes that are self-reinforced, straightforward, and guaranteed health security. ( Hacker, S. Jacob, January 11, 2007) My new health care system will expand coverage, create better incentives for quality and efficiency, and link health insurance to individuals, rather than to their place of employment. It will be guided with personal responsibility for one’s own health as well as being ensured the health and welfare of all our citizens. It would make health insurance mandatory for all U. S. citizens, offering subsidies to help defray the cost of premiums. Our American citizens would benefit the most from this new health care system. A failure to act rising health care costs will jeopardize our public’s health and undercut out international competitiveness. A failure to make affordable health changes available to our Americans who are currently uninsured is morally indefensible. If we use this new health care system, we will be lowering the health care costs and the premium costs of medication. This will suit the needs of all American citizens, with low income or no income that have little or no health coverage at all. (Nichols, Len, July 2007) My new health care system would not have any existing populations with disadvantages, there would be an affordable plan for all American citizens, and this new system would leave no individual uninsured. Each American citizen will have coverage for their medical and medication needs, with affordable premium plans to suit their budgets. This new proposal would solve current challenges such as; 1) access to health care- the first major challenge, people being uninsured are less likely to receive appropriate care, for such things as chronic illnesses, and are more likely to die from diseases. 2) cost- the evidence suggests that the cost of health care in the United States is greater than necessary to allow us to achieve the levels of health and longevity we now enjoy. Insurance companies and the government play such prominent roles in financial health care, patients and doctors have less incentive to consider the extra costs of optional tests or treatments. Taking on this fist challenge we will take in consideration that the uninsured are not all alike; they include people, who have low income, people who are not poor but have costly health conditions, those employed but don’t get offered an group health insurance. Taking on the second challenge, could be the challenge hard to overcome. Increasing access or improving quality, may increase rather than reduce total cost. Patients, doctors, and hospitals must be given incentives for choosing cost-effective approaches. The best way to reduce the financial burdens in our health care system is to deliver cost-effective health care throughout the entire system. Today with the diversity of people, companies can’t create just one benefits program that meets everyone’s needs. The employer decides how much money it will allot per employee for the year for benefits; once that figure is assigned the employees can research and compare the costs of various health insurance options. (Bernanke, S. Ben, June 16, 2008) In conclusion this new health care system would provide affordable and reliable health care for every American. This would also provide the much needed coverage for those who need it the most. Having health coverage for every American would also cut down on the amount of people who wait to see a doctor until they are too ill, who then have to go into the emergency room, which then costs the health care system and government more money.
